Neural stem cells are undifferentiated cells that are located in limited areas of central nervous system. These cells have proliferation and self-renew ability and can be differentiated into neurons and glial cells. Mature nerve cells do not have proliferative ability; and due to the limited number of nerve stem cells, injuries to the nervous system are not recoverable. The purpose of this revi...

Differentiation of human neural progenitors into neuronal and glial cell types offers a model to study and compare molecular regulation of neural cell lineage development. In vitro expansion of neural progenitors from fetal CNS tissue has been well characterized. Despite the identification and isolation of glial progenitors from adult human sub-cortical white matter and development of various c...

Human neural progenitor cells (hNPCs) are currently believed to have important potential for clinical application and basic neuroscience research. In the present study, we have developed a new technique for expansion of human neural progenitor cells in vitro. We showed that the cultures of hNPCs in monolayer could keep the same features with that growing in neurospheres. These cells expressed t...

Bisphenol A (BPA), an endocrine-disruptor, is widely used in the production of plastics and resins. Human perinatal exposure to this chemical has been proposed to be a potential risk to public health. Animal studies indicate that postnatal exposure to BPA may affect neocortex development in embryos by accelerated neurogenesis and causing neuronal migration defects. The detailed phenotypes and p...

Alcoholism is associated with cognitive deficits and loss of brain mass. Recent studies have indicated that neural progenitor cells proliferate throughout life forming neurons, astrocytes, and oligodendrocytes. The dentate gyrus is one neurogenic region of the adult brain containing neural progenitor cells. To determine if binge ethanol (EtOH) exposure alters neural progenitor cell proliferatio...

During brain development, neural progenitor cells extend across the thickening brain wall and undergo mitosis. To understand how these two completely different cellular events are coordinated, we focused on the transcription pattern of the nestin gene (Nes), which encodes an intermediate filament protein strongly expressed in neural progenitor cells. To visualize nestin expression in vivo, we g...

Primitive neuroectodermal tumors (PNETs) are pediatric brain tumors that result from defects in signaling molecules governing the growth and differentiation of neural progenitor cells. We used the RCAS-TVA system to study the growth effects of three genetic alterations implicated in human PNETs on a subset of neural progenitor cells that express the intermediate filament protein, nestin. The ge...

We have developed a good manufacturing practice for long-term cultivation of fetal human midbrain-derived neural progenitor cells. The generation of human dopaminergic neurons may serve as a tool of either restorative cell therapies or cellular models, particularly as a reference for phenotyping region-specific human neural stem cell lines such as human embryonic stem cells and human inducible ...

Adult hippocampal neurogenesis results in the formation of new neurons and is a process of brain plasticity involved in learning and memory. The proliferation of adult neural stem or progenitor cells is regulated by several extrinsic factors such as experience, disease or aging and intrinsic factors originating from the neurogenic niche. Microglia is very abundant in the dentate gyrus (DG) and ...

Stem/progenitor cell based therapeutic approach in our daily routine clinical practice, has been elusive dream in medical sciences and improvement of stem cell homing as one of major challenges in cell therapy programs, has been considered a promising milestone. It has been proved that stem/progenitor cells exhibit a homing response to injured tissues/organs, mediated by interactions of chemoki...
